Principles and Application of Pneumatic Springs

The Pneumatic Spring Subcommittee of the SAE Spring Committee recently updated the information report J511a relating to Pneumatic Spring Terminology for the SAE Handbook. It is also in the final stages of writing a Manual on the Principles and Application of Pneumatic Springs (HS J42). This paper is a review of that manual. It outlines basic principles, types, applications, special cases, and associated equipment. It will also apprise suspension engineers of the general capabilities and limitations of pneumatic springs. The production of these springs is also covered.
